Thepresent invention relates to screens and particularly to the construction of'frames therefor.

7 An object of the invention is to provide an improved screen frame construction. I

A further object is to provide a screen frame with which the wiremesh may besimply and quickly connected; and which'will I provide an assembly positive against dis- 10 lodgment of one element from the others.

A still further object is to provide in a screen of this character improved inter tting clamping parts for the screen material'which may be readily disengaged one from the Mother for wiring or rewiring the same. i A further object is to provide a screen frame, the improved construction of which is such as to lend itself to the ready manufac-j ture of the members thereof by extrusion or rolled metal process. Y

A still further object is to provide improved frame members all the parts whereof are formed integrally of a homogeneous metal construction. 7 7

Further objects are to provide an improved insect-proof construction in screen frames with frames of inter-fitting partswhich will be neat in appearance and which may be easily adapted to sliding or stationary fit A still further object is to prolong the life of the screen and to protect the screen at points of greatest wear. A screen made in acordance with the principles of the invention comprises frame members having an interfitting relation to each other for clamping the screen material therebetween; which frame members consist of grooved frame members-proper and improved splines nesting in said grooves.

The disengagement of the splines from the grooves may be'facilitated by providing lips extending from one side thereofaffording membersunder which a tool may be inserted fora prying action thereagainst.

The splines and frame members proper may be further provided with means :for lockingthe edges of the screen material in within a window frame and which may be- 1929; Serial no. 370,437.-

enhance-the neatnessof appearance of the I connection between the screen cloth 'and frame. g V V T I Thls appearance maybe further enhanced 'insetting thisside the depth of the screen and lip so as to present thesurface of the spline andthe associated frame member in the same plane, i l v Tenacity of grip between the frame memhers and splinesmay'befincreased by forming the grooves slightly undercutand the splines of complementary c ros'ssectiong this construction" also cooperating with the interengagingkeys and keyways to this end.

The improvement in the construction wherebythe frames adapt themselves to extrusion manufacture is the extension of all parts of the members thereof in right lines longitudinally ofgthe frame members The frames may be made up of combinations of frame members all of which are of the same construction, or may be made of various combinations of the frame members hereinafter described and illustrated in the accompanying drawings.

an embodiment ofthe invention conforming to the principles laid down in the foregoingfparagraphs' is illustrated in the accompanying drawings, 1n whlch:

Figure 1 shows a window fragmentarily in the frame of which is mounted a screen made in accordance with the present inven tion,"

FigureQ; is a section on the line 2-2 of Figure 1, showing the connection between the screen wire and the screen frame and also a sliding connection of the'screen frame a the windowframe and having a compensating flange extending into the slideway,

Figure 4 shows the invention in a somewhat diflerent aspect and showing a compensating fittingor attaching flange on the edge of the screen frame and a modified form of interengagingkey,and keyway, 7 T

Figure 5 isa fragmentary 'viewshow'ing a slideway in perspective, and

Figure 6 is a View similar to Figure 3 with the compensating stripomitted.

Referring to the drawings in detail, 10-

designates the window frame in which the slideways 11 are 1n0unte'd,12 designatesthe screen which is comprised of meshed screen material 13 and side'framemembersist; and top and bottom frame-members '14. These side frame members may-be formed of any suitable material as metal, either extruded, rolled or otherwise produced. 7

The screen material 13 may be connected to the frame by suitably anchoring the'edges thereof in grooves 15 formed in one face of the frame membersiproper as designatedby the numeral 16. These grooves are preferably slightly constricted or undercut as at 17, the undercut portion of which may be more orless curved or circular in contour, the outlet of the grooves beingbetween sub stantially straighuparallel walls 18"and '19.

An interengaging connection'between the spline and the frame member properis provided and a further engagement isprovided in the-nature ofinterengaging keys 2.0 and 3 keyways 21 in the-present showing the keys beingfornied in the bottom of the grooves and the l;eyways in the bottom of the spline. These engaging keys and keyways, are preferably angular in cross-section inorder to form a biting grip of the screen material between the interengaging frame members and the spline.

The frame members are provided with shoulders 22 and 23 on either side of the grooves, the shoulders one,;as the shoulder 23 being depressed compared with the spaced shoulder sufiiciently to accommodate the screen materialand overhanging inserted between-the same and the screen material for dislodging the spline may operflanges, as shown at 25 in Figure 3 of the drawings or at25 'in Figure l. ,This compensating flangemay be used as asl'ide ridmg ma suitable shdewayQG which may consistbfflanges spaced apart a surlicient dis- .tance tomaccommodate the. compensating flange 25. "This compensating flange when des gned to be used asa slide may be inset the thickness of the outermost flange-constitutingithe slidewayso as to give a continuity of surface between the frame member and the slideway; This shdeway may also be pro- V1 ded with an attaching flange 27 adapted for use'in attaching the same to the window frame." This flange may be provided with a pluralityof apertures such as indicated at 2'8,

in Figure 5 of'the drawings- The compensating flange when used for at tachmg the-screenin a non-sliding manner to a window frame may-when elected provide the compensatingfl ange as at 25 in Figure linaplane-with the surface 22 of the frame 7 member -with whichit is associated and suitable apertures provided in this flange for attaching hinges, latches or other-accessories for attachingthe same to the window frame so that the frame may be readily attached and detache'th-or swung outwardly fromthe window frame.

The spline maybe either ofsolid forma tion, as in FigureS, or it may be hollo'w, as in Figure 4. The construction shown in Figure 6 is'particularly adapted for top and'bottoni frame members, although it may also be used as side frame members under certain circumstances and where the frame is to be used in astationary position within the window frame, -one; or'more, or even all of the frameanembers may lie-provided with flanges such as is shown at 2501' 25 respectively, in Figures. g

The above description, together withthe illustrations, are to be considered asmere'ly illustrative of the invention and itis to be clearly understood that various changes indetails of construction .may benmde inthe manufacture of the invention within the scope of the invention as hereinbefore setforth and hereinafter claimed.
